    I am trying to change a few of the tuning parameters on our AIX5.1 ML3 p660
    running in 64bit mode for the dba. When I view the current settings using
    vmtune (and/or vmtune64), I see a value for numclient as NaNQ%. What does
    this mean?

    number of valid memory pages = 3145712 maxperm=INF% of real memory
    maximum pinable=80.0% of real memory minperm=INF% of real memory
    number of file memory pages = 0 numperm=NaNQ% of real memory
    number of compressed memory pages = 11127 compressed=INF% of real
    memory
    number of client memory pages = 0 numclient=NaNQ% of real memory
    # of remote pgs sched-pageout = 0 maxclient=INF% of real memory

    When I try to change the settings for maxclient using vmtune, it also goes
    into a NaNQ%. If I then try to change the maxperm and minperm, they go into
    a NaNQ% and the system hangs and requires a hard reboot. The dba recomended
    the settings for minperm=2% and maxperm=3%. This box is running the
    database only and no other applications.
